| 實物特徵: | Vertical distribution of eggs of the macadamia nutborer Ecdytolopha torticornis Meyrick (Lepidoptera: Tortricidae) and its preference of oviposition sites within and between macadamia cultivars were studied in Turrialba, Cartago, Costa Rica, in 1992 (N = 6 939). E. torticornis eggs were found throughout the foliar parts of the tree, but fewer eggs were laid in the crown top than in the mid or lower crown. Differences in the horizontal distribution of the eggs were not significant, albeit more eggs were found in the outer positions. The numbers of eggs found within the crowns of different clones were similar, implying that the nutborer has no preference for a particular cultivar. |
